Re: PyNGL vector_map with irregular grid

FYI: There is a pyngl-talk mailing list [pyngl-talk_at_ucar.edu]

The leap from NCL graphics to PYNGL graphics is not
that great. Look at:
       http://www.ncl.ucar.edu/Applications/trimesh.shtml
for the appropriate resources.

===============================
The pyngl solution is at:
       http://www.pyngl.ucar.edu/Examples/gallery.shtml
See "Contouring on non-rectangular Grids"

Good luck
